A synchronous Cloud Batch task uses a caller-stable job ID. If its worker exits after submission, retry resubmits the same ID and fails with `409 ... already exists`, even if the first job is active or succeeded. On Airflow 3.3+, the operator saves the canonical name before waiting. Retry fetches only that task-owned job: wait if active, restore success, resubmit after `NotFound`, or reject other terminal states. Fresh and deferrable execution, `durable=False`, and older Airflow behavior do not change. ## Testing The regression test drives the real task state accessor and `execute()` with a local hook stand-in. <details> <summary>Raw retry proof</summary> ```console $ AIRFLOW_HOME=.build/cloud-batch-proof-home uv run --project providers/google pytest providers/google/tests/unit/google/cloud/operators/test_cloud_batch.py::TestCloudBatchSubmitJobOperator::test_retry_reconnects_to_running_job -xvs # upstream/main E google.api_core.exceptions.AlreadyExists: 409 Job projects/testproject/locations/us-central1/jobs/test already exists =================== 1 failed, 1 warning in 113.59s (0:01:53) =================== # this branch PASSED =================== 1 passed, 1 warning in 92.69s (0:01:32) ==================== ``` </details> --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (GitHub Copilot CLI, GPT-5.6 Sol) Generated-by: GitHub Copilot CLI (GPT-5.6 Sol) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) --- * Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#pull-request-guidelines)** for more information.
